Abstract
The utility model discloses a suction draught fan of a non-woven fabric lapper melt-blow device, wherein the suction draught fan is placed on one side of a lapper curtain. The power of the suction draught fan is 110 kW, and the flow rate of the suction draught fan is 40000-55000m<3>/h. Therefore, through the improvement on a suction draught fan used for a melt-blow device system, the power and the flow rate of the suction draught fan are improved so as to improve suction quantity. Therefore, flying fibers in the process of stretching of fibers can be reduced, the fiber diameters are reduced, fiber quantity is increased, a water-repellency effect and flexibility of products are improved, and tensile strength and burst strength of non-woven cloth of a melt-blow method are enhanced.
Description
Technical field
The utility model relates to the field of textiles technology, refers in particular to a kind of sucktion fan of nonwoven fabric lapper melt-blowing equipment.
Background technology
Under certain screw speed condition, the meltblown fibers diameter reduces with the speed of drawing-off hot-air or the increase of temperature.But along with the increase of air velocity or the temperature of hot-air, the thinner while that will be drafted from the meltblown fibers of spinneret orifice ejection also can produce more short fiber.This just requires aspiration must be enough large, otherwise individual other short fiber can't be adsorbed on lace curtaining, and the willow catkins flying in the air of formation bunchy.When the willow catkins flying in the air that fly away from suction areas drop on the fiber of one-tenth lace curtaining of operation again, will form white dot, thereby affect quality.But it is 55KW that traditional 1.6M melts and sprays production line sucktion fan power, and flow only has 20000m3/h, total head 5920Pa.When producing willow catkins flying in the air in production process, solution is the generation that the hot attenuating blast flow of Spiral fan or gas flow temperature are reduced to avoid willow catkins flying in the air, the consequence of doing like this is thinner that the fiber string diameter can't be drafted, on final SMS product, melt-blown micro fibre unit are coverage rate is little, cause the SMS hydrostatic pressing to be difficult to be improved, simultaneously because superfine fibre does not carefully cause the product feel more coarse.Therefore, should retrofit to sucktion fan, to increase aspiration, reduce the fiber string diameter, satisfy the production requirement.
The utility model content
In view of this, the utility model is for the disappearance of prior art existence, its main purpose is to provide a kind of sucktion fan of nonwoven fabric lapper melt-blowing equipment, can reduce willow catkins flying in the air in the tensile fiber process, reduce the fiber string diameter, increase fiber number, that improves the SMS product refuses the water effect, and strengthens TENSILE STRENGTH and the bursting strength of melt blown non-woven.
For achieving the above object, the utility model adopts following technical scheme:
A kind of sucktion fan of nonwoven fabric lapper melt-blowing equipment is positioned at into lace curtaining one side, described sucktion fan power 110KW, and flow is 40000-55000m
3/ h.
As a kind of preferred version: the total head 5071Pa of described sucktion fan.
As a kind of preferred version: described sucktion fan melts and sprays the equipment of production line for being fit to 1.6M.
As a kind of preferred version: described sucktion fan with become to form between lace curtaining the negative-pressure air-suction zone.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, by the melt-blowing equipment system is retrofited with sucktion fan, increases sucktion fan power and flow, to strengthen aspiration.By this, this sucktion fan can reduce the willow catkins flying in the air in the drawing of fiber process, reduces the fiber string diameter, increases fiber number, and that improves product refuses water effect and pliability, and strengthens TENSILE STRENGTH and the bursting strength of melt blown non-woven.
For more clearly setting forth architectural feature of the present utility model and effect, be described in detail below in conjunction with accompanying drawing and specific embodiment.
Description of drawings
Fig. 1 is the principle schematic of the utility model preferred embodiment.
The accompanying drawing identifier declaration:
10, become lace curtaining 20, air draught zone
30, cold air 40, fiber
50, spinning pack
The specific embodiment
The utility model as shown in Figure 1, the sucktion fan of nonwoven fabric lapper melt-blowing equipment is positioned at into lace curtaining 10 1 sides, be applicable to 1.6M and melt and spray production line, this sucktion fan power 110KW, flow is 40000-55000m3/h, total head 5071Pa.
Sucktion fan after remodeling is along with the improvement of parameters has the following advantages:
The first, sucktion fan with become between lace curtaining 10 to form negative-pressure air-suction zone 20, the sucktion fan of remodeling makes into the air draught zone 20 negative pressure increases of lace curtaining 10, in the certain situation of drawing-off hot-air speed, compensation cold air 30 amounts of surrounding enviroment will increase, fiber 40 is in time obtained later on cooling afterwards by the moment drawing-off of high speed thermal current by spinning pack 50 ejections, fiber 40 is not easy to produce willow catkins flying in the air in drafting process.
The second, simultaneously due to the air draught zone 20 negative pressure increases that become lace curtaining 10, compensation cold air 30 amounts of surrounding enviroment increase, be conducive to the raising of drawing-off hot-air speed, the raising of drawing-off hot stream temperature and the raising of melt temperature, finally be conducive to drafted thinner of fiber 40, fiber 40 string diameters can drop to the 0.01-0.02 micron by original 0.04-0.05 micron.Because the melt extrusion amount is certain, fiber 40 string diameters attenuate at double, mean that namely fiber 40 quantity that are ejected into in lace curtaining 10 unit ares are double, in the SMS product, the area coverage of melt-blown micro fibre 40 is double, is conducive to the most at last the SMS product and refuses significantly improving of water effect.Be mainly used at present due to the SMS product on the side leakage limit of baby paper diaper, refuse significantly improving of water effect and will make the leakproofness of paper diaper better.
Three, along with the raising of drawing-off hot-air speed, be conducive to improve fiber 40 brute forces and improve the heat bonding degree between fiber 40 in fibre web, thereby improving TENSILE STRENGTH and the bursting strength of melt blown non-woven.
Four, meltblown fibers 40 string diameters drop to the 0.01-0.02 micron by original 0.04-0.05 micron, and it is more soft that the product feel will become, and for being widely used in baby paper diaper side leakage limit fabric, soft sense of touch will be more suitable for the tender skin of baby children.
Design focal point of the present utility model is, by the melt-blowing equipment system is retrofited with sucktion fan, increases sucktion fan power and flow, to strengthen aspiration.By this, this sucktion fan can reduce the willow catkins flying in the air in the drawing of fiber process, reduces the fiber string diameter, increases fiber number, and that improves product refuses water effect and pliability, and strengthens TENSILE STRENGTH and the bursting strength of melt blown non-woven.
The above, it is only preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, therefore every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification made for any of the above embodiments, equivalent variations and modification.
